list-available-tools
Retrieve and organize all available tools from connected MCP servers for toolset creation. Access detailed metadata and reference tools using 'namespacedName' or 'refId' for streamlined integration.
Instructions
Discover all tools available from connected MCP servers. Returns structured data showing tools grouped by server for toolset creation. Tools can be referenced by 'namespacedName' (e.g., 'git.status') or 'refId' (unique hash). Example: Call with no parameters to see all tools organized by server with detailed metadata for each tool.

Implementation Reference
- Handler function that executes the tool logic: formats available tools from toolsetManager if discovery available, else returns error. Returns both text (JSON) and structured content.handler: async ( // eslint-disable-next-line @typescript-eslint/no-unused-vars args: any ) => { if (deps.discoveryEngine) { const structured = deps.toolsetManager.formatAvailableTools(); return { content: [ { type: "text", text: JSON.stringify(structured), }, ], structuredContent: structured, }; } else { return { content: [ { type: "text", text: "❌ **Tool discovery not available**\n\nDiscovery engine is not initialized. Server may not be fully started.", }, ], isError: true, }; } },
